The A1058, known locally as the Coast Road, is a major road in Newcastle upon Tyne and the adjoining borough of North Tyneside in the North East. It runs from the Newcastle Central Motorway to the coast, terminating between Whitley Bay and Tynemouth. From west to east it connects Newcastle city centre with Jesmond, Heaton, Wallsend, Battle Hill, Howdon, Meadow Well, North Shields, Whitley Bay and Tynemouth. The road has existed since December 1924, when it was opened by then-transport minister Wilfrid Ashley.For five miles (8 kilometres) of its eight mile (12.5 kilometre) route it is a full urban dual carriageway with grade separated interchanges and, for four of those miles, a 70 mile per hour national speed limit (the one mile segment passing Heaton has a 50 mph speed limit). However, it is not built to full UK standards for motorway-style roads, as it has too many entrances and exits and most of its sliproads have pedestrian crossings.
The A1058 interchanges with two other major roads, the A19 and the A167. The interchange with the A167 on the Newcastle Central Motorway was constructed along with the motorway itself finishing in 1973, and has remained largely unchanged in the fifty years since.The Coast Road has crossed the A19 at what is now called Silverlink Interchange since 1967, when the first Tyne Tunnel finished construction. However, Silverlink Retail Park itself has only existed since c. 1990; it is accessible directly from the interchange's roundabout, along with Cobalt Business Park, a significant economic organ of the area. Prior to 2016 there was no direct through route on the A19; traffic on that road had to use the roundabout with traffic to and from the A1058 and the retail park, which caused the interchange to be congested and dangerous. Beginning in 2016 and completing construction in April 2019, National Highways constructed the first three-level stack interchange in the North East, meaning both roads now have a free flowing through route.
